FIELD OF THE INVENTION

The present invention relates generally to the field of fluid containers, in which the bottle must be squeezed or tilted to release the flow of fluid to allow for ease of drinking, washing, and/or cleaning and is particularly applicable to sports bottles, or the like.

BACKGROUND OF THE INVENTION

In recent years, the number of health-conscious individuals has grown tremendously. In addition, research into the importance of clean water for hydration and other uses during health-improving activities: walking, hiking, biking, camping, and other outdoor activities has led to an increased need for fluid delivery devices that can provide fluids through a secure and hygienic means. Conventional fluid delivery devices, such as water bottles, are useful for various purposes in activities such as athletic, outdoor, recreational, or other uses. Typically, such devices are designed for a user to carry water, electrolytic fluid replacement drinks, or any type of liquid or, in some cases, powders or other materials. In many cases, these devices are used to enable active people: walkers, hikers, riders, and campers to drink or replenish fluid loss without stopping their particular activity. Additionally such devices may be used by these individuals as a source of water to clean themselves, their utensils and tools.

Depending on the type of fluid dispensing system, constant or frequent use of fluid containing devices and bottles can lead to damage to, for example, the pull-valve, or loss of a screw-type cap or pop-on/pop-off lid. Furthermore, for squeeze-type containers, the frequent deformation of the container can lead to structural failure of the walls of the container. Additionally, the ability to control water flow to clean or wash can be difficult as the fluid dispensing device must be tilted at a particular angle and/or squeezed to initiate the flow of water.

Additionally, transmission of germs and the inclusion of foreign material into the fluid becomes an increased risk from the constant and repetitive touching of the mouth to the pull-valve or rim and/or the repetitive opening of the container, exposing the contents to the environment.

Furthermore, the mechanical stress of repetitive opening and, in some cases, squeezing the bottle, may result in damaged or lost parts and a shortened product life span.

As a result of the above-stated problems and desires, there is a need for a fluid container, without the limitations of conventional fluid containers.

In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. In addition, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

SUMMARY OF INVENTION

The present invention comprises a pressurizable fluid container which may be further comprised of a body, a cap, a means for pressurizing the contents of the body and a dispensing mechanism, such as a spray nozzle.

In one or more embodiments, the pressurizable fluid container comprises a fluid containing body. The body may have chamfered or straight edges and may have a threaded portion to connect to a cap or lid. The threads may be interior or exterior to the body. The cap or lid may also have a threaded surface to screw on to the body. The threads may be interior or exterior to the cap.

In one or more embodiments, a plunger mechanism may be used to pressurize the contents of the body. The pressurization may be accomplished through a number of ways, for example, a plunger mechanism may consist of a handle, a shaft and a stopper. The plunger mechanism may be a vertical push-pull plunger. The plunger mechanism may be a horizontal push-pull plunger. The stopper may also be activated by a hinged or “squeeze-type” mechanism. In one or more embodiments, the contents may be pressurized by an external pump or a compressed gas canister.

In one embodiment, a vertical push-pull plunger is pushed repeatedly into and pulled repeatedly out of the body in order to pressurize the contents. Once pressurized, the contents may be released by activating a valve which allows the contents to travel up a relief tube and out the spray nozzle of the device.

In one or more embodiments, the valve may be used to open a fluid pathway to allow fluid in the body to escape. The valve may be a teeter valve which pivots on a transverse axis. When one side of the teeter valve is depressed, the fluid pathway to the nozzle is open. When the teeter valve is released, the fluid pathway is closed.

When the fluid pathway is open, the fluid may be directed to a nozzle. The nozzle may allow for adjustment of the release amount or other characteristics. In one embodiment, the nozzle may be a spray nozzle. The spray nozzle may be adjustable to allow for a fine mist, a stream of fluid, or a dispersed pattern to be released from the device.

The fluid pathway may be simply on-off or it may be controllable, as a variable flow.

In one embodiment of the present invention, the device may be used for hydration.

In one embodiment of the present invention, the device may be used for cleaning and washing.

In one embodiment of the present invention, the device may be used for applying a fluid or fluid-like substance to a surface or substrate.

In one embodiment of the present invention, an uptake adapter may be inserted between the relief tube and the relief tube extension to improve the outflow of liquid and increase the structural integrity of the relief tube extension.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. Therefore, the foregoing is considered as illustrative only of the principles of the invention.

Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

Other objectives, features and advantages of the invention will become apparent from the following description and drawings wherein.
